Lactantius' treatise the de opificio dei has received little attention from classical scholars in modern times. There are two main reasons for this. First, Lactantius is regarded essentially as a Christian apologist and therefore of interest primarily to theologians and students of Christian history. Second, that work which has been done on the treatise has tended to the view that the opif.'s interest for scholars lies largely in the question of its written sources, its main such source, according to several commentators, being the Hermetic body of writings. Both of these reasons need re-examining. With regard to the first, it is unfortunate that the only surviving works of Lactantius are his specifically Christian treatises, written after the outbreak of persecution in A.D. 303. As such they represent only a portion of his work, being composed in the last two decades of a long life. The basis of his reputation as a rhetorician, a reputation which secured him his appointment as professor of Latin rhetoric at Nicomedia under Diocletian, must have been his earlier works, which pre-date his conversion in c. 300.
